I need a developer who can configure the official WhatsApp Business API so my team can handle real-time customer support through live chat. The goal is simple: when a visitor messages our business number, the conversation should flow straight into an agent-friendly dashboard (whether that’s a custom front end, a CRM module, or a reputable third-party chat workspace—I’m open to your recommendation). Core requirements • Register and verify the WhatsApp Business account, then activate the Cloud API or on-prem setup. • Create or connect a live-chat interface where multiple agents can pick up, transfer, and close conversations. • Implement webhook endpoints for message events, delivery receipts, and agent activity logs. • Add basic agent presence indicators and typing status so customers know someone is responding. • Provide concise documentation and a brief hand-off session so we can manage the solution ourselves. We are not looking for automated FAQs, ticketing workflows, or outbound notification campaigns right now; the immediate focus is human-led chat. If your experience includes Node.js, Python, or PHP middleware, Meta’s Graph API, and OAuth/SSL best practices, you’ll be able to move quickly. Please outline your proposed stack, estimated timeline, and any similar projects you’ve shipped.
